Abstract

A method of post chemical mechanical polishing (CMP) cleaning to remove a CMP residue from a surface of an object is disclosed. The object is placed within a pressure chamber. The pressure chamber is pressurized. A supercritical carbon dioxide process is performed to remove a residual CMP residue from the surface of the object. The pressure chamber is vented.
